David you are messing with black arts you know nothing about. As you stripped it, from what i could see, the plunger was half down. This means the piston head is halfway down the cylinder, so the gas charge is not enough to make it fire as the piston is in the wrong place. The usual cause of this is the O rings are worn and dont seal the cylinder on each firing, making the piston stop before returning. Its a simple fix, two new O rings.
Hi Robert if you follow me you will understand I have a go at most things and learn as I go I never claim to be an expert I just show what I'm doing but with help like you have just given I get better and so do the people that watch so thank you for your input I will be giving it a go
@@dmgladden Thanks for your comment and appreciation. As you say we all learn by sharing advice and observations. Its usually the lower ring on the cylinder assembly, but while its apart you may as well change the one on the fan casting too (they are different sizes. Unlike a car engine where the crank drives the pistons back up the cylinder to the next firing stoke, the Paslode relies on a good combustion, as the remnants of the charge go under the piston, from an exhaust port in the exhaust. Its a bit like the concept of a two stroke, but in reverse. If the rings leak significantly, there is not enough exhaust gas to drive the piston back up. To test this, check the pin is right back so the piston is in firing position. Try firing it. Itwill fire but not a second time if this is the fault as the exhaust gas has not driven the piston back up. You can confirm this by checking to see if the driver blade is close to the tip. It should return right into the chamber. If the piston has not returned its usually the O rings.
@@roberttill3787 that is a very detailed account of what to do and why, thank you again im sure this will help not just me but many more that read your comments.
@@dmgladden Having just watched your video again due to it appearing in my feed, there are a couple of points i could add. Firstly the noise is not it "charging up" as you said near the end, its the fan spinning as the cylinder closes. The fan is in the combustion chamber and stirs the fuel/air mixture to ensure an evenly mixed mixture. Secondly it looks like it could be a later model where the lower O ring has been replaced with metal piston rings. If thats the case theres only ONE O ring, and thats on the fan casting (cylinder head). Thirdly i would also be suspicious of the spark plug. I check fan activation, and for a spark as i rebuild it before the cylinder is fitted back on the handle assembly.
With the cylinder separated from the handle (and gas removed!) it is easy to test the electrical part of the gun by inserting a battery and pressing in the small spring, Illlustration #27 part #404448 and operating the trigger. The fan should come on and you should be able to see the spark jump. If no spark check circuit board, spark unit or fan.
Yes Richard I agree Half a job I am not saying I could have got it working but a bit more as you say open tool testing was needed. So not a "Nice try" as some comments said in my opinion.
Do you mean the leaf spring with the roller ball on it that gets pushed down by the alloy piston housing (when it moves back about 10 mm) when you press on the nose? it sits in front of the fan mount pivot. 17:01
Nice repair quandry. I would make sure that the fuel nozzle is not blocked. And if that fails then check that the spark for the fuel is present(magneto?). Then if thats not it then i would paint a thin layer of JBWeld over the hairline crack on the surface opposite the firing chamber. It must have a spark for the fuel...what else could it be??? 🤔
Seems to me that the other micro switch in the circuit (the one that’s activated when you push the fire button) is at fault. All very well getting the fan to run when you push the nose in ( proving that micro switch no.1 works) but micro switch no.2, activated when you push the fire button, has to be good too or else the gun won’t work. These micro switches have a hard life and fail fairly regularly. Trouble is, they are not repairable being totally sealed and tiny as well. A new circuit board is required.
Hi David, quick question. I have the same nail gun and I just cleaned it. I followed your paslode service Tutorial and everything went very smooth. Only problem is, my gun is no longer firing. I took it apart and pushed down on the metal clip to start the fan. The fan will start but makes no sound and no spark. The battery is brand new. Any ideas?
When all else fails see if the high voltage unit is working. With the cylinder removed you can depress the switch by hand, watch the fingers when the fan starts and check for spark.
I have one of these that I bought brand new and it never sank a single nail flush no matter what setting I used. Is there a typical problem that would cause that? I've never disassembled it. Just put it up on the self about 20 years ago. New sub by the way.
I don't think you can call yourself a repairer, you didn't check the HT coil the best way is take off the spark lead on the head hold it about 2mm away, then depress the switch with the roller on it the fan will start, hold it down then push the trigger switch in, and a spark should jump across the gap. If not the High tension coil can be faulty. Its not rocket science, if you have gas, fan running, and spark it should fire. The unit dosen't need Compression to fire it, it works by filling a chamber with gas and air at the correct mix...then ignition....
I've had that problem, you can take the gas out, leave the battery in and press down on the nose, put your ear near the back end and pull the trigger and you should hear the tick of the spark plug. If thats all good check the stem adaptor, its the red plastic gas tip locator, My one had a crack in it so solved it with a new one, Also change the O rings there are two of them
what do you mean? My gun is doing the same thing and it had only been used 3 times. It looks brand new. Last time it was used, we changed the gas canister but the gun wouldn't work. I assumed someone had bought the gas and returned it to the store with a replaced spent canister). So now, about 3 or 4 years later, I finally bought a new gas canister for it to make sure the gun worked before selling it. But it still doesn't work. I took it apart and noticed thin blue. . .don't know what to call them. . . they were like little rings around the two screws that hold the thing that slides back and forth??? Anyway, they were broken and I took the bits out of the holes the screws went in. Is that what you are talking about? If not what?
Hi David - on my IM65 nowadays it only fires about 4 pins then wont fire. I've put new original Paslode gas in and new NMH batteries. I've changed the charger to a NMH charger ( from Ni-Cad) just in case. The fan goes ok. After about 4 shots the flashing green light goes solid. (The old NiCad batteries would go all day) It would seem like a battery issue but I keep buying new batteries and the same thing happens. Any ideas?
I repair these guns and it very much sounds like you have a fan fault. The fan takes a high load from the battery, and if theres a problem with it, one moment the gun is fine the next it flashes a battery fault
It's your gas catrage cover. It's not locked properly. Look at the video. When you press the gun, it comes up; it's not sparying the gas in the piston. No gas, no combustion.
Harry the cover is designed to do that. It rocks on the pin that holds it shut. The can comes backwards as the cylinder closes, the cover moves up, and round converting the backwards movement to a vertical movement. It presses the can adapter and makes the can discharge a shot of gas. The door is operating properly when it does this.
Hi, great vids David. Happy to subscribe. What do you think. I bought the mi350 second hand, it’s in good condition, but I’m a bit fussy, should I buy new plastic outer casing, or am I just being a muppet?
If your a Muppet then so am i as its something i would think of doing but in all reality 1 day on site and it will be tge same best thing is keep it working like new not looking like new. Thanks for the great comment
I have that gun and it’s doing the same thing yours is doing Intermittent it will shoot then it won’t pull the trigger I found the only part that has failed when I replace it and if problem goes away I will let you know what it is
Can you do a video on replacing the bumper inside the main body of the IM350 please? I was able to follow your video to take my gun apart and put it back together, but there were bumper pieces galore that came out of it and that may explain why it won't fire anymore. Thanks very much
Hi Furzhanal. Thanks for watching and for showing interest in the whole shop. I have a Playlist dedicated to the workshop. Where you will see every aspect of the workshop
@@dmgladden Yeah...........I've never used one of those, but I can see with your video, it would be a problem with a small crack in the housing to cause a problem!
A Great BIG Thank you to Neil from Yorkshire who was so determined to thank me despite not having Paypay he posted £10 directly to me. Also a big thanks to all the wonderful grateful people whom thank me through my , www.paypal.com/paypalme/Davidglad makes helping people worth while THANK YOU ALL
Check the spark unit, mine was working fine but after being in storage was gassing up and fan was going but no firing, did basic strip down, removed spark unit and cleaned, cleaned the point on the back plate the spark arcs against, reassembled and bingo, fires every time
As i have never used ether of them i couldnt comment but should i ever get the chance i will do a comparison video as i have been using the Paslode for around 15 years
If you've ever seen a parts diagram for the Dewalt you will know why I run away from these guns. The Paslode is a much simpler design but still has its problems
New Paslode guns are CRAP!!!! I use to swear by them when they first came out. ( When they were black, with the round battery). Now, both the framer & trim gun SUCK ! The tip won't even stay on the trim gun. It slips off every other time you shoot it. (If it even shoots at all!!!). CRAP!!!!!!!!!!!😡🤬🤬🤬
Paslode makes unreliable garbage. Get a Senco. Have 2 paslodes, neither work and both were used very little, less than 500 nails. The Senco is like 30 years old and works flawless, the paslodes have been very finicky and can't be relied on for a business, unless you want to be poor
Hi thanks for the comment and trying to help its always appreciated, no it did turn out to be the cylinder as i swapped it with mine and all worked imperfectly but its gone into the box as spares it wont go to waste
Nice try shame it's that throw away world we live in, I know those guns are expensive my lads have got them, It's just the price of perts and labour nothing is repaired most of the time, but there you are !!!
Yes Brian that it is but I'm not one for throwing things away but sometime tools get to the end of there life and they will have done enough work to have paid for them selves many times over
when dismantling/reassembling the two halves of the gun the spindle coming out of the fan motor can easily bend a fraction causing the fan to slightly catch the insides when running ,then the spindle breaks inside the motor and you need a new motor. I know it happened to me 6:54

I think you should have tried checking the trigger switches board assy for continuity. The switches go bad.

Why didnt you try the chamber off yours to rule out the trigger and electrics werent at fault?
I did just not on camera
@@dmgladden ah ok, so was the trigger end at fault or did the other top bit fire on yours
Try the spring on the trigger either bend it or shim it the wheel wears and it won't fire,that flat spring @ 17:01
Thanks for the tip but no its compression as i swapped the tops over with another and the bottom half works fine
Nice repair quandry. I would make sure that the fuel nozzle is not blocked. And if that fails then check that the spark for the fuel is present(magneto?). Then if thats not it then i would paint a thin layer of JBWeld over the hairline crack on the surface opposite the firing chamber. It must have a spark for the fuel...what else could it be??? 🤔
How can you tell its not the spark generator?
you did well mate, honest man

Was it working ok before you stripped it down?
David Gladden yeah.
When all else fails see if the high voltage unit is working. With the cylinder removed you can depress the switch by hand, watch the fingers when the fan starts and check for spark.
this may sound stupid, but did you put nails in before testing, as once the nails are low there is a safety bar that stops firing happening.
I have one of these that I bought brand new and it never sank a single nail flush no matter what setting I used. Is there a typical problem that would cause that? I've never disassembled it. Just put it up on the self about 20 years ago. New sub by the way.
No it should do, on the tip you should adjust the slide by loosening the two bolts slide it up and tighten again this should work
back to dealer.
Could also be a seal or exhaust/ reed damage issue.
I don't think you can call yourself a repairer, you didn't check the HT coil the best way is take off the spark lead on the head hold it about 2mm away, then depress the switch with the roller on it the fan will start, hold it down then push the trigger switch in, and a spark should jump across the gap.

My problem was literally dirt build up on the rear frame preventing the spark from being able to arc against the point, quick clean and all sorted
@@mattlustig3564 that is exactly why Paslode say they should be regularly service cleaned.
If he gets really stuck I can always take it to get it serviced because I’m $160 but it’s a lot better than throwing away $1000 gun
I've had that problem, you can take the gas out, leave the battery in and press down on the nose, put your ear near the back end and pull the trigger and you should hear the tick of the spark plug.
If thats all good check the stem adaptor, its the red plastic gas tip locator, My one had a crack in it so solved it with a new one, Also change the O rings there are two of them
What if it doesn't click?
Where are the other o ring located?
My motor isn't running it just stopped mid use.Any tips Dave?.
Sounds like a power issue, check everything to do with battery.
Thank you.👍
Hi Dave I cleaned the sensors that touch the battery and it works now.They must have corroded over Christmas when it wasn't used.
Cheers kris
mine did same gas was not getting in placed a thin polystyrene in works fine now
